So far many researchers have emphasized the future importance of intercultural understanding and aims to better understand the Japanese language, as well as educate secondary education students in culture classes. However, the proposed action and reporting of these targets in culture classes were hard to say. Therefore, in this study it was decided to explore the possibility of a poem as a representative of Japanese culture to achieve the aims above. As a result, it was possible to feel the pleasure expressed by the spring and it is possible to cultivate the imagination by reading the poem. Then, in the comparative activities, to discover the common points and differences of the country, it was possible to give a "notice" to the diversity of culture. Understanding different cultures begins with "enlightenment". In other words, noticing the "differences" to individuals or by the addition of values and ideas. There often arises a feeling of criticism and resentment and conflict, but by including empathy and resonance leads to a discovery and development of a new self. And this is exactly what makes it possible to reach mutual understanding and compromise.
